There doesn't appear to be a set time line in place, but TV One is expected to launch an HD simulcast of its SD network soon on several Comcast / Time Warner Cable systems. The channel, which is a self-proclaimed "entertainment television network for African Americans," will first hit TWC's NYC region and Comcast systems in Boston, Chicago, Portland, OR and Seattle. We're told that more regions should find the HD iteration of the channel beginning in early January 2009, and at least initially, some 20% of the content will be shot and aired in high-def; if all goes well, that figure should rise to 40% by 2010.
